Blake Shelton is constantly talking about drinking whiskey, but could it be that he’s drinking on the job? Fellow coach Christina Aguilera seems to be implying as much!

During her November 28 appearance on Jay Leno, Christina certainly alluded to there being more than iced coffee in the Starbucks cups her competitors are always sipping from — especially Blake!

“Oh, Blake. I’m not sure he knows exactly what’s going on,” she joked. “He likes to keep that cup nice and full and iced … I could be a cocktail waitress on that show on the side for all the guys.”

Jay responded to Christina’s dig with some cat noises, but Christina denies being catty about her boys and their drinking habits. “No, it’s not — it’s funny actually,” she laughed.

For someone who is reportedly scared to go on Jimmy Kimmel Live because she thinks the talk show host will embarrass her, Christina sure let it fly when it came to her rival coaches. Then again, they can certainly dish it out themselves!
